In this report, we analyzed the cellular and noncellular findings of bronchoalveolar lavage fluid in 18 cases with IPF, 12 patients with Sar and 9 healthy volunteers as conirols, using immunohistochemicat staining, we also have estimted collagen typeⅠ and type Ⅲ semiquantitatively in transbronchial lung biopsy specimens from 25 patients with IPF and 10 normal lung tissue. The aim of this investigation is to select the criteria for evaluating the disease actiity.

本文对18例IPF、12例Sar和9例正常对照者的支气管肺泡灌洗液中细胞成份和非细胞成份进行了检测和分析，同时对10例正常肺和25例IPF患者经支气管肺活检的肺组织标本，应用免疫组化方法、半定量剂检测其中Ⅰ型胶原和Ⅲ型胶原的含量结合临床治疗效果，对有助于疾病活动性判断的指标进行了筛选和进一步的评价。

The immunohistochemistry showed that ERK and JNK had the similar location which the cytoplasm and nucleoplasm were immunostained in the ovogonium and spermatogenous cells.

在免疫组织化学的观察中，ERK和JNK在卵原细胞和精原细胞中均为阳性反应，且定位相似：细胞质及细胞核核质呈阳性反应，核仁阴性。

He type of ossein in group B was mainly type Ⅰ collagen while that in group A type Ⅱ and it exhibited as a process of fiber formation in group C. The reason for why TGF-β〓 can promote ossification induced by BMP is that can promote the differentiation and proliferation of mesenchymal cells to supply more target cells for BMP, promote the differentiation and proliferation of mature osteocytes and chondrocytes, inhibit metalloproteinase to decrease the destruction of bone tissue and promote calcification of bone matrix.

GF-〓能促进BMP骨诱导作用主要因其能促进间充质细胞的分裂增殖为BMP提供丰富的靶细胞、促进成熟骨及软骨细胞的分裂增殖、促进骨细胞产生Ⅰ型胶原而抑制软骨细胞产生Ⅱ型胶原，抑制金属蛋白酶的活性以减少组织破坏、促进基质钙化等作用而使骨生成能力增加，提示它和BMP具有协同作用。

With tile ovary maturing, the orifice was narrowed because of tile ovary growth at last fused completely. The gynoecium is composed of a single carpel.(1) In tile series developmental sections of ovary, the ovular primordium was initiated on the adaxial meristem when tile mouth of ovary was formed.

子房由1枚心皮构成；(4)从子房发育过程的切片看，该植物的胚珠是在子房发生后不久发生的，子房上的圆孔形成时，从近轴侧的分生组织发生胚珠原基，由胚珠原基分化出珠被与珠心。

AIM: To explore the matching degree of in situ expression and serum level of pepsinogen C in different gastric mucosal biopsies, and to evaluate its value in the diagnosis of gastric cancer.

目的：通过对不同类型胃黏膜活检组织胃蛋白酶原C的表达和血清胃蛋白酶原含量的检测，研究二者的匹配程度及其在胃癌筛查与诊断中的价值。

In order to overcome the shortcomings of acellular dermal matrix used as tissue engineering scaffold material, such as bad permeability, low degradation speed, and strong immunogenicity, a new type of collagen scaffold was prepared by applying various chemical, biological and physical comprehensive methods to deal with pigskin. The microstructure of the scaffold was observed under photomicroscope and scanning electron microscopy, and the in vitro degradation time, permeability, tensile-strength, porosity, shrinkage temperature were tested.

为了克服猪脱细胞真皮基质作为组织工程支架材料渗透性差、降解速度过慢、免疫原性较强等缺点，采用多种化学、生物与物理综合方法处理猪皮制备了一种新型天然胶原支架材料，通过光学显微镜、扫描电镜观察以及体外降解时间、透水汽性、拉伸强度、孔隙率、收缩温度等的测定，对其性能进行了研究。

The internationally popular provitamin B5 also stimulate the proliferation of fibroblasts and help tissue curing, slow down skin aging.

其中国际上流行的天然成分维他命原B5还可以刺激纤维原细胞的增殖并帮助组织修复，减缓皮肤老化。

Results Valvular interstitial fibroblasts were most often spindle-shaped in collagen lattice and there was no difference between normal and rheumatic mitral valve tissues.

结果 正常及病变二尖瓣组织来源的成纤维细胞在胶原凝胶中的形态改变差异无显著性，在胶原凝胶内呈长梭形。

METHODS: Fresh bovine tendo calcaneus collagen was dispersed in 0.5 mol/L acetic acid, co-precipitated with chitosan and lyophilized. Dry membranes were cross-linked in 0.05% glutaraldehyde for 24 hours. In vitro its degrading rate was measured by use of collagenase degrading test. The chitosan-collagen membrane was implanted to subcutaneous dorsal sites of SD rats. After implantation, histocompatibility, vascularity and degradation were observed in vivo.

以酸溶法制备胶原溶液，添加一定比例的脱乙酰化几丁质，冻干成膜，0 。0 5 %戊二醛溶液浸泡交联，行体外酶降解实验，检测其耐受酶降解能力；将制备的几丁质-胶原蛋白膜包埋于 36只 SD大鼠皮下，术后 3、5天，1、2、3、4、6、8和 12周取材，检测其组织相容性、血管化能力及材料在体内降解情况。

They also had a more adverse atherothrombotic profile, with higher tissue-type plasminogen activator and plasminogen activator inhibitor-1 (PAI-1) antigen.

他们也具有更不利的动脉粥样化血栓形成的曲线：更高的组织纤溶酶原激活物和纤溶酶原激活物蛋白抑制剂1 (PAI-1)抗体。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.
